Goat Rock Beach sits at the north end of Sonoma Coast State Park, where the Russian River meets the Pacific just south of Jenner. California State Parks says the park runs 17 miles of Highway 1 from Bodega Head to the Vista Trail north of Jenner. The coast is made up of beaches separated by rocky headlands, with more than a dozen access points from the highway.
The rock and the river
The beach is named for Goat Rock, a huge outcrop at its south end that is barely attached to the mainland by a narrow isthmus. The state uses that strip as a parking lot. Signs ban climbing the rock or trying to walk around it. Blind Beach is on the other side of it.
The river's mouth is at the north end of the beach. In summer, a sandbar usually separates the river from the ocean. When the river rises in late fall and early winter, the sandbar breaks open and the beach splits in two. Wikipedia says the protected northern section becomes a pupping area for harbor seals. The Russian River State Marine Reserve and State Marine Conservation Area protect the estuary.
Wildlife, and keeping your distance
Harbor seals, sea lions and sometimes elephant seals haul out here, along with river otters and several kinds of gulls. The state recommends staying at least 50 yards from marine mammals, especially during pupping season.
Stay out of the water
Goat Rock is not a swimming beach. The sand drops steeply into an underwater trench that runs parallel to shore and creates strong rip currents.
Know before you go
State Parks lists the beaches where dogs are allowed in Sonoma Coast State Park: Marshall Gulch, Carmet, Schoolhouse, Portuguese, Duncan's Cove, Wright's, Furlong Gulch, Shell, Blind and Russian Gulch. Goat Rock is not on that list. Drones may not be launched, landed or flown in the park's Sonoma-Mendocino Coast District. The Salmon Creek Ranger Station is on Highway 1, about halfway between the north and south Salmon Creek beach lots. Fog often burns off by midday, but bring layers. Winter is whale-watching season on this coast.
